Lens antenna and lens antenna array
First Claim
1. A lens antenna mounted on a mobile unit, which is in a non-body of rotation form, and in which, at a lens antenna-mounted position, the direction and magnitude of inclination and curvature of the surface of the mobile unit as well as the direction and magnitude of inclination and curvature of a radiation-side surface of the lens antenna are within ±
- 20%, and a focal-side surface of the lens antenna is formed with respect to the radiation-side surface in such a way that the radiation-side surface and the focal-side surface have a quasi-optical configuration as a lens antenna.

Abstract
The invention has for its object to achieve a high-performance lens antenna which can be integrated with the external (surface) shape of a mobile unit with no damage to the appearance of the mobile unit and is easy to manufacture and assemble at relatively low costs. To accomplish this, the invention provides a lens antenna mounted on a mobile unit, in which the radiation-side surface thereof and the focal-side surface thereof are each of a quasi-optical shape as a lens, and which is in a non-body of rotation form.
